Title: Derivative prepared by treating carbon nitride with acid and its production
Inventor: KAWAGUCHI MASAYUKI
IPC: C08G73/06
Filed: 1989-05-15
Abstract: PURPOSE:To obtain a polymeric compound having a narrow wavelength range of light emission and an increased strength by treating a specified carbon nitride with a mineral acid. CONSTITUTION:A layered acid-treated carbon nitride of formula II (wherein 8.0<=alpha<=10.0; 3.0<=beta<=10.0; and 1.0<=gamma<=4.0) is obtained by treating a carbon nitride of formula I (wherein 2<=x<=4.0<=y<=8) with a mineral acid. The carbon nitride as the starting material can be obtained by reacting cyanuric chloride with either ammonia or melamine and heat-decomposing the product at 400-600 deg.C. A carbon nitride desirable as the starting material is one synthesized from a cyanuric chloride/ammonia system, melamine alone, or a melamine/ cyanuric chloride system. The mineral acid used is nitric acid, hydrochloric acid, hydrofluoric acid, sulfuric acid or the like, and its concentration is desirably higher than 1N.

Title: Method for separating/recovering living rubber of disposed rubber-lined metal tube
Inventor: TAKADA KENJI
IPC: B29B17/02
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To simply separate and recover a lining rubber of a disposed rubber- lined metal tube, without environmental pollution by extruding the lining rubber to the outside of the metal tube after soaking the disposed rubber-lined metal tube in liquid nitrogen. SOLUTION: In a metal tube lined with a rubber having a comparatively thick wall disposed from a food processing factory or the like, first the rubber- lined metal tube is soaked in liquid nitrogen, and a lining rubber is extruded to the outside of the metal tube, when the lining rubber is separated from the metal tube to be recovered. In this method, the lining rubber becomes brittle due to a low temperature to lose its adhesion by cooling the rubber-lined metal rube at a low temperature through soaking in the liquid nitrogen, or the lining rubber becomes contracted, and the lining rubber is separated from the metal tube. Consequently, the lining rubber can be extruded from the metal tube to be recovered by pressing one end of the lining rubber after soaking it in the liquid nitrogen.  The lining rubber separated and recovered is reused as rubber scrap, and the rubber resources are effectively utilized.

Abstract: PURPOSE:To form an uneven surface on a sloped ground by strongly laying a columnar block having a crosswise groove extending in the longitudinal direction on its left and right-handed both sides and a plate block having connected recessions on its four side faces. CONSTITUTION:An angular columnar block 1 has a crosswise groove 4 continuously extending in the longitudinal direction of its left and right both sides and a vertical groove 8 connecting to its both ends.

Title: Temperature control device
Inventor: SUWA MASATO
IPC: H05B3/20
Filed: 1998-04-30
Abstract: PROBLEM TO BE SOLVED: To control the temperature of a temperature control object so that the temperature of the temperature control object such as a semiconductor wafer on a base plate is made uniform over the whole region by forming cut-out parts for reducing the width in the bent part of a heating resistance wire body arranged in the form of a bent single layer on the surface of the base plate. SOLUTION: A disc-like thin film heater on a base plate has independent heating resistance wire bodies 100, 200-to which electricity is individually supplied in the center and the periphery, the first heating resistance wire body 100 has a plurality of heating elements, and is constituted so as to have the same heating value by supplying the same electric power. These heating resistance wire bodies 100, 200 are constituted by insulating for example, a ZrO2 covered nichrome wire with a polyimide resin, in the bent part of which cut-out parts comprising slits 40 are formed along the extending direction. Since the resistance value in the bent part is increased and the heating value is also increased, the temperature distribution along the extending direction of the heating resistance wire bodies 100, 200 is made small.  The width in the bent part is preferable to be cut so as to be gradually widened from the inside to the outside, and thereby, the deviation of current in the width direction in the bent part is moreover reduced.

Title: Normal vision mirror
Inventor: KISHIDA MASAHIRO
IPC: A47G1/04
Filed: 1993-05-24
Abstract: PURPOSE:To provide a mirror which reflects the same image as a normal vision image. CONSTITUTION:A normal vision mirror 1 is constituted by forming a zigzag irregularity 3, which has ridges and grooves at a certain angle, for example, 90 deg., on a transparent base material 2, and providing this irregular face with a mirror face 4. When an image is projected as shown by an arrow, it is reflected at an incline of 45 deg., and further is reflected at an opposite incline, so the image is feflected in the condition that it is rotated completely one time, so it is reflected in the same way as a normal vision image.

Title: Surface wave filter
Inventor: YAMADA HIROMICHI
IPC: H03H9/145
Filed: 1984-06-12
Abstract: PURPOSE:To reduce spurious radiation by constituting an input electrode with a normal interdigital electrode and constituting an output electrode with an interdigital electrode applied with crossing width weighting so as to eliminate unbalance of direct waves. CONSTITUTION:Since the output electrode 24 is subjected to crossing width weight, the area of the electrode is large. Thus, a capacitance with a shield electrode at the back face is large. A direct wave output Vs01 extracted from a bus bar 32 placed between an input electrode 23 and the output electrode 24 is a voltage division of the level of the direct wave from the electrode 23 to the 24 through a capacitance Cs1 between both the electrodes and a capacitance C01 between the bus bar 32 and the 2nd shield electrode at the back face. This is similar as to a bus bar 33. In this case, the relation of the capacitances is Cs1<<C01 and since the C01 is nearly 5 times the capacitance of the normal output electrode in using a PZT substrate, the direct wave output is decreased to nearly 1/5. Since the direct wave amount propagated to the bus bars 32 and 33 is reduced largely, the amount of unbalance of the propagated direct wave is reduced largely.

Title: Rolling method of thick plate
Inventor: ASAHI ICHIROU
IPC: B21B1/38
Filed: 1978-10-03
Abstract: PURPOSE: To elevate the yield rate by making the plane form after width rolling approximate to the rectangular form, after the longitudinal section form before width rolling is gradually changed extending over the end part.  
     CONSTITUTION: The lateral edge form of rolling material after width rolling becomes a drum or spool shape depending upon whether the width expanding ratio is not less than or not more than 1.5, respectively. In case of the former, the longitudinal section form of rolling material before width rolling is made to be thick 16A gradually extending over the front and rear ends from the part 300W1000mm of the front and rear ends of this section. In case of the latter, the aforesaid part is gradually made to be thin 16B. This variation of the part in thickness is molded by varying the roll void in the course of rolling of the molding pass. The drum and spool shapes can be prevented by carrying out width rolling of the rolling material 16A and 16B of such shapes as the foregoing.

Title: Antimicrobial fiber and method for antimicrobial treatment of fiber
Inventor: TANIGUCHI HIROAKI
IPC: A61L2/16
Filed: 1991-04-25
Abstract: PURPOSE:To obtain a fiber containing a specific compound composed of a quaternary ammonium salt and an amino acid-based surfactant without causing discoloring and fading and inhibiting antimicrobial performance. CONSTITUTION:Antimicrobial fiber is obtained by treating a textile material with a treating liquid containing a quaternary ammonium salt (e.g. organosilicone quaternary ammonium salt) and an amino acid-based surfactant, e.g. an N-acylamino acid salt (e.g. N-lauroylsarcosine sodium salt) expressed by the formula [R<1> is 8-18C alkyl; X<1> is COO<-> or SO3<->; A<1> is Na, K, Li, N(CH2 CH2OH)2 or H; (m) is 1 or 2]. Thereby, the antimicrobial fiber treated with the quaternary ammonium salt in which its cationic groups are partially blocked with the N-acylamino acid salt is obtained. As a result, the antimicrobial fiber without losing fluorescence of the fiber even in the case of fiber subjected to fluorescent bleaching treatment and causing problems of discoloring such as yellowing and inhibiting the antimicrobial properties of the quaternary ammonium salt is obtained according to the aforementioned treatment.
